Chemgeek And Waterbear, Question On Safety

[Matt38]

Years ago we had a discussion on the safety of chlorine. I know generally you guys like chlorine and so do I. After reading this AMA on reddit and digging down into the publications, my concern about chlorine has resurfaced. Are you up on the latest research and what is your interpretation? The researcher suggests that silver ion may be a safer alternative (buried in the responses). Not being an experimentalist, I'm not able to quickly quantify the bladder cancer risk. I don't mind spending a much greater amount of money on frequent water and silver ion cartridge changes, but I'm wondering if those have their own unknown and not well discussed risk from the MPS. I realize it still uses chlorine, but much much less.

edit:here is the referenced article on bladder cancer http://aje.oxfordjournals.org/content/165/2/148.abstract

It's very easy to focus on things that don't pose very much risk based on statements like "twice the risk" even if you are still much more likley to get hit by lightning.

Thanks!
